Answer: 3 and -1/2.
Step-by-step explanation:
You can represent any linear inequality using any of the following forms:
[tex]x > b[/tex]
[tex]x < b[/tex]
[tex]x \geq b[/tex]
[tex]x\leq b[/tex]
When the sign is pointing towards x, it means that x is greater than b.
The line under the greater sign means that x can also equal b.
In your case, b is -4., as that is the point at which numbers are no longer part of the set. An open dot over -4 is a way to represent that -4 is not a part of the solution - so x cannot equal -4.
The options given:
- 3: is greater than -4
- -5: is not greater than -4
- -1/2: is greater than -4
- -4.5: is not greater than -4
- -4: is not greater than -4.
So, your solutions are 3 and -1/2.
